Archigrammitis Friderici-et-pauli
''Archigrammitis friderici-et-pauli'' is a species of fern in the family Polypodiaceae, subfamily Grammitidoideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). It is native to Borneo and Sulawesi. Taxonomy Konrad H. Christ first described this species in 1896, under the name ''Polypodium friderici-et-pauli''. This is the basionym of ''Archigrammitis friderici-et-pauli'', published by Barbara S. Parris in 2013. Christ caused some confusion over the use of the epithet ''friderici-et-pauli''. The previous year, 1895, he had published the name ''Davallia friderici-et-pauli''. This is the basionym of the accepted name ''Acrosorus friderici-et-pauli'', published by Edwin Copeland in 1906. In 1904, Christ again published the name ''Polypodium friderici-et-pauli'', this time making reference to ''Davallia''. Hence ''Polypodium friderici-et-pauli'' Christ (1896) is a synonym of this species, whereas ''Polypodium friderici-et-pauli'' Christ (1904) is an ille ...
